# Thevenin's Theorem

In many practical applications, it is always not necessary to analyse the complete circuit. To analyse the circuit, the voltage,current or power in only one resistance in that circuit is highly enough. To find the current in a resistor or a load, thevenin's theorem is quite useful.

## Thevenin's Theorem Statement

Thevenin's theorem states that for the purpose of determining the current in a resistor, R_{L} connected across two terminals of a network which contains sources of emf and resistors, the network can be replaced by a single source of emf (**E**_{TH}) and a series resistor (**R**_{TH}), to find the current passing through the load **R**_{L}

## Explanation

**step 1:**Remove the load R_{L} between the circuit terminals A an B.

**step 2:**Calculate the open-circuit voltage(**V**_{oc} = **E**_{th}) which appears across terminals A and B, when they are open i.e) when (**R**_{L}) is removed.

**step 3:** Short circuit the battery and find the Thevenin resistance **R**_{TH} of the network as seen from the terminals A and B.

**step 4:**Connect **R**_{L} back across the terminals A and B from where it was temporarily removed earlier.
